WILLIAM RIGKETTS, OF CINCINNATI, OHIO.

STOP-COCK.

SPECIFICATION forming part of Letters Patent No. 312,165, dated February 10, 1885.

Application filed June 11, 1884 (No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM RIoKETTs, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Stop-Coeks; and I dohereby declare thefollowing to be a full,clear,a-nd exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to such stopcocks as are constructed with a waste-valve which opens on closing the cock to let the water out ofthe pipes above the cock. One object of my improvement is to so construct the wastevalve that it shall be less liable to leak or to injury due to the cutting action of sand or grit in the water. Another object is to so construct and apply the waste-valve that it forms at the same time a packingfor the spindle of the cock. These objects I accomplish by the construction specifically pointed out in the claims at the close of this specification.

In order that my invention may be clearly understood, I have illustrated it in the annexed drawing, and will proceed to describe it, as applied to a stopcock the main valve of which consists of a rubber plug, the stem of which is engaged by an eccentric on a spin dle at right angles to itan old style of stop cook.

The drawing represents a sectional elevation of such a stop-cock.

The spindle A, for operating the main rubber plug-valve B, is fitted near its upper end in the cap 0, and at its lower end in the perforated diaphragm D of the case E of the stop-cook. The spindle is provided with a collar, F, having a port, f. This perto rated collar of the spindle constitutes the waste-valve proper, and is seated against a ring-seat, G, which has a port, g, and is secured screwed home.

against the top of cap 0, around the hole through which the spindle passes. Port 9 registers with a passage in the cap leading to the waste-pipe 0 thereof. The ring-seat G may be made of leather or rubber,0r of metal, in which case it is ground to make a close joint with the collar F. In every case the ringseat is fitted close against the cap to prevent leakage past it.

In order to hold waste-valve close against its seat, I apply a stiff spiral spring, H, to the spindle between the diaphragm D and collar or valve F, the spring being so long that it will be somewhat compressed when the cap is The waste-ports f and g are so arranged that they registerwhen the main valve B is shut, as shown in the drawing. When the main valve is open by spindle A, the portf moves over a solid portion of the ring-seat.

It will be readily observed that no sediment can lodge between the flat waste-valve and its fiat seat to cause a leakage or cut the valve.

I claim as my invention 1. The combination, substantially as before set forth, of the spindle of a stop-cock, provided with a collar having a waste-port, and a tired ring-seat having a similar waste-port.

2. The combination, substantially as before set forth, of the spindle of a stop-cocl ,p1'ovided with a collar having a waste-port, the fixed ring-seat having a similar waste port, and being arranged above the collar against the cap, and the spring which holds the collar in close contact with the ring-seat.

I In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM RIOKETTS.
